Cylinder Platen, 6 ½” Diameter

• Free floating bearing platen seats under test pressure.

Used when testing 6” (152 mm) or 4” (101 mm) diameter concrete cylinders in compression. Platen is manufactured from steel with all components plated for corrosion resistance.

Upper cylinder platen used when testing 6” (152 mm) or 4” (101 mm) diameter concrete cylinders in compression. Its bearing platen is 6 ½” (165 mm) in diameter, through hardened to HRC 55 or greater, plane to .0005” (.02 mm), has scribed concentric circles for specimen centering, and is hard plated for corrosion resistance. The bearing block is closely held in its spherical seat, but is free to tilt in any direction and seat securely under load.

Lower platen is 1" thick and 6.5" in diameter. The platen is hardened to a Rockwell hardness of 55 HRC and is precision ground to maintain planeness within .0005" in any 6.00" direction. The surface is scribed with concentric circles for test specimen centering and electroplated with nickel for wear and rust resistance.

Note: An optional spacer is required for testing 4” (101 mm) diameter cylinders.
